i am using
asterisk-1.2.24
libpri-1.2.5
zaptel-1.2.21
and
astguiclient_1.1.12-3
. I have 10 agents using SIP (VOIP) . my problem is customer is not able to here out agent's voice . i have 1MBps bandwidth connection and test with 3 different voip provider but the problem is same.

with 4 agents the load avg is 1.37

CPU type and speed? amount and type of RAM?

have you run iftop to see how the bandwidth is moving?

Are you using a firewall?

thanks for your reply

cpu is dual core 1.8GZ
RAM size is 3 GB DDR2
i m not using any firewall

i haven't install iftop
the OS i m using centOS without graphic

Have you tried the Zoiper softphone with IAX accounts instead of SIP?

please post your internet up/down speed

and post the codec that you are using to dial out


describe the agent pc , because that must be caused by the agents sound cards

i haven't try with IAX account , now i will try that too.

and my internet speed is 1MBps up and 900KBps down
and i am using free g729 codec

and i do have p4 machine with 512 RAM and inbuilt sound card for agents pc

if you can post your sip.conf config files to the forum

is it is the problem with astguiclient version ?
as if i dial manualy from the soft phone directly then the voice is clear
but when i am using the agc page then i m facing this type of problem .
